It goes without saying that I'm an Amanda Walker fan (you have fans!), and this game was everything I hoped for. I played it with my wife, who hasn't really played much IF at all, and it went pretty much perfectly.
I've been thinking a lot about two-person puzzles (I ended up with http://www.suberic.net/~tahnan/puzzles/substitutions-welcome.pdf, if puzzles are your thing). so I'm thrilled to see someone else doing the same.
